portion of the second panel extending from the frame as the first
panel pivots with respect to the frame and moves between the first
panel closed position and a first panel folding open position and
the second side portion of the second panel slides along the path
and pivots with respect to the frame as the second panel moves
between the second panel closed position and a second panel folding
open position.
[0020] In various embodiments, operating the fenestration unit in
the sliding mode includes causing a releasable latch to be in a
latched position coupling the second side portion of the first
panel to the frame to cause the first panel to remain in the first
panel closed position; causing a fold hinge to be in a disconnected
state to cause the second side portion of the first panel to be
disconnected from the first side portion of the second panel; and
causing an operable transfer mechanism to be in a transfer position
coupling the first side portion of the second panel to the frame to
enable the second panel to be slidable about the path. Operating
the fenestration unit in the folding mode includes causing the
releasable latch to be in a release position uncoupling the second
side portion of the first panel from the frame; causing the fold
hinge to be in a connected state to cause the second side portion
of the first panel to be pivotally connected to the first side
portion of the second panel; and causing the operable transfer
mechanism to be in a release position uncoupling the first side
portion of the second panel from the frame.

DETAILED DESCRIPTION
[0034] Persons skilled in the art will readily appreciate that
various aspects of the present disclosure can be realized by any
number of methods and apparatuses configured to perform the
intended functions. It should also be noted that the accompanying
drawing figures referred to herein are not necessarily drawn to
scale, and may be exaggerated to illustrate various aspects of the
present disclosure, and in that regard, the drawing figures should
not be construed as limiting. Moreover, while embodiments including
two movable panels are disclosed herein, other embodiments
including a fenestration unit having more than two movable panels,
and in addition no, one or more than one fixed panels, are also
contemplated.
[0035] Various aspects of the present disclosure are directed
toward fenestration units that are adapted to provide for
versatility in how they may be opened. Fenestration units according
to the present disclosure may be adapted for sliding doors, sliding
windows, and any other fenestration unit having one or more sliding
panels. An exemplary fenestration unit 10 in the form of a door 10
is illustrated in FIG. 1. As shown, the door 10 includes a frame 12
and a plurality of panels, such as first panel 14 and second panel
16. The door 10 is configured to define a boundary between an
interior space and an exterior space, such as an interior space of
a home and the elements outside of the home for example, while
providing access through an opening in the fenestration unit
between the interior and exterior spaces. As described in greater
detail below, door 10 is configured for operation in either or both
of a first or sliding mode, or a second or folding mode, to provide
the access between the interior and exterior spaces.
[0036] As shown in FIG. 1, the first panel 14 and the second panel
16 are both situated within and supported by the frame 12. In
various embodiments, the second panel 16 is configured to slide
relative to the frame 12 to provide an opening in the door 10
during the sliding operating mode. For example, as shown in FIG. 2,
the door 10 is shown in a partially open configuration where the
second panel 16 has been slid partially open to define a partial
frame opening 18. The first panel 14 is configured to be pivoted
relative to the frame 12, and the second panel 16 is configured to
be pivoted and to slide relative to the frame, such that the first
and second panels can be hinged, folded or otherwise pivoted and
slid open to increase the size of the opening in the door 10 during
the folding operating mode. For example, as shown in FIG. 3, each
of the first and second panels 14 and 16 are shown folded open or
otherwise pivoted and slid open relative to the frame 12 to define
a relatively full frame opening 18. It is to be appreciated that
the first and second panels 14 and 16 can be configured to fold or
pivot outwardly toward an exterior and/or inwardly toward an
interior.
[0037] Thus, in various examples, the door 10 may include a
plurality of panels such as 14 and 16, where both of the panels are
configured to slide and/or pivot relative to the frame 12 of the
door. Such a configuration provides for a door 10 that is adapted
for providing a relatively large opening in comparison to
conventional doors having sliding panels. Such a configuration also
provides for a door 10 having one or more panels such as 14 and 16
that can slide (e.g., to provide an opening where pivoting the same
to provide for a larger opening is unnecessary). Doors or other
fenestration units in accordance with these examples provide
enhanced ingress and egress capabilities. They are also
structurally robust.
[0038] With continued reference to the embodiment shown in FIG. 1,
the frame 12 of the door 10 includes a sill 20, a head 22, a first
jamb 24, and a second jamb 26. The sill 20 is a structural frame
element that generally defines a bottom portion of the frame 12,
while the head 22 is a structural frame element that generally
defines a top portion of the frame. The sill 20 and the head 22
each generally extend laterally between the first and second jambs
24 and 26, as shown. The first and second jambs 24 and 26 are
structural frame elements that extend vertically between the sill
20 and the head 22. In various examples, the head 22 is supported
by each of the first and second jambs 24 and 26. The first jamb 24
generally defines a first side portion of the frame 12, while the
second jamb 26 is situated opposite the first jamb and generally
defines a second side portion of the frame.
[0039] FIGS. 4A and 4B illustrate the interior or panel-facing
sides of the sill 20 and head 22, respectively. As shown, the sill
20 and head 22 include tracks 30A and 30B, respectively, that guide
the second panel 16 along paths between closed and open positions.
Tracks 30A and 30B include first portions 32A and 32B,
respectively, that define generally linear paths extending between
the first and second jambs 24, 26 (i.e., in a direction generally
parallel to the major planar surfaces of the first and second
panels 14, 16). In various embodiments, and as shown for example in
FIG. 1, the second panel 16 of door 10 can be coplanar with the
first panel 14 of the door when the first and second panels are in
closed positions (e.g., the angle between the first and second
panels can be 10 degrees or less). In embodiments with this
coplanar closed configuration feature of door 10, and as described
in greater detail below, tracks 30A and 30B can include second
portions 34A and 34B and third portions 36A and 36B, which extend
from the first portions 32A and 32B, respectively, in generally
transverse directions. As described in greater detail below, the
first portions 32A and 32B of tracks 30A and 30B, respectively, are
configured to facilitate lateral and sliding translation of the
second panel 16, and to guide the second panel along a path
generally parallel and adjacent to the first panel 14 as the second
panel moves between its closed and open positions. Second portions
34A and 34B and third portions 36A and 36B of tracks 30A and 30B,
respectively, are configured to facilitate generally transverse
motion of the second panel 16 when the panel is near its closed
position, and to guide the second panel to and from its closed
position coplanar with the first panel 14. The tracks 30A and 30B
are configured to receive one or more components of the second
panel 16, such as one or more wheels, pins, bolts, riders, roller
bearings (e.g., unidirectional, multidirectional, and/or
omnidirectional) or other transfer mechanisms to facilitate this
movement. In some examples, the tracks 30A and 30B are formed as
grooves in the sill 20 and head 22, respectively. In some examples,
the tracks 30A and 30B are formed as concave grooves configured to
accommodate convex riders (e.g., such as convex wheels and/or
rollers). In other examples the tracks 30A and 30B are formed as
convex protrusions configured complementary to concave riders
(e.g., such as concave wheels). In other embodiments (not shown),
second panel 16 is parallel to but not coplanar with the first
panel 14 when the second panel is in its closed position, and the
tracks need not include the second portions 34A, 34B and third
portions 36A, 36B or other structures to accommodate the coplanar
feature. In some examples, one or more of the tracks 30A, 30B
extend the entire width of the sill 20 and head 22, respectively,
such as from the first jamb 24 to the second jamb 26. In some
examples, the one or more tracks 30A, 30B extend along only a
portion of less than all of the sill 20 and head 22,
respectively.
[0040] Referring back to FIG. 1, the illustrated embodiment of the
first panel 14 includes a first rail 40, a second rail 42, a first
stile 44 and a second stile 46. The first rail 40 is a structural
element that generally defines a bottom portion of the panel 14,
while the second rail 42 is a structural element that generally
defines a top portion of the panel. The first rail 40 and second
rail 42 each generally extend laterally between the first and
second stiles 44 and 46, as shown. The first and second stiles 44
and 46 are structural elements that extend vertically between the
first rail 40 and the second rail 42. The first stile 44 generally
defines a first side portion of the panel 14, while the second
stile 46 is situated opposite the first stile and generally defines
a second side portion of the panel 14. In the illustrated
embodiment, the first rail 40, second rail 42, first stile 44 and
second stile 46 form a frame that supports a glass or other panel
48.
[0041] Second panel 16, similar to first panel 14, includes a first
rail 50, a second rail 52, a first stile 54, a second stile 56 and
a glass or other material panel 58. The first rail 50, second rail
52, first stile 54 and second stile 56 of second panel 16 are
configured and function in manners that are the same as or similar
to the corresponding components of the first panel 14. For example,
the first stile 54 of the second panel 16 generally defines a first
side portion of the panel, and the second stile 56 generally
defines a second side portion of the second panel.
[0042] In some examples, when the door 10 is in the closed
configuration, the opening of frame 12, which is the region defined
between the sill 20, the head 22, and the first and second jambs 24
and 26, is at least substantially blocked or otherwise obstructed
by the first and second panels 14 and 16, as those of skill will
appreciate. As such, when in the closed configuration, the door 10
operates to separate the exterior space and the interior space. It
is to be appreciated that while fenestration units such as door 10
described herein are referred to in conjunction with an interior
and an exterior space, the fenestration units may be configured to
separate first and second rooms or other areas of a structure. When
the illustrated embodiment of door 10 is in the closed
configuration, the first stile 24 of the first panel 14 is
proximate (e.g., in or close to actual contact with) the first jamb
24 of the frame 12. Additionally, the second stile 56 of the second
panel 16 is proximate (e.g., in or close to actual contact with)
the second jamb 26. Additionally, as shown, the second stile 46 of
the first panel 14 is proximate (e.g., in or close to actual
contact with) the first stile 54 of the second panel 16 when the
door is in the closed configuration.
[0043] The first panel 14 is mounted to the frame 12 for rotation
or pivotal motion about the second side portion of the first panel
with respect to the frame. In various embodiments, the first stile
44 of the first panel 14 is hingedly coupled to the first jamb 24
of the frame 12 to provide this functionality. In the example
illustrated in FIG. 5, the door 10 includes one or more pivot
assemblies, such as one or more hinges 60, which are coupled with
the first stile 44 and configured to pivotally couple the first
panel 14 to the first jamb 24 of the frame 12. In the illustrated
example, the one or more hinges 60 are positioned along the height
of the first jamb 24 from the sill 20 to the head 22. While the
pivot assemblies are shown in FIG. 5 as hinges, it will be
appreciated that any of a variety of actuation mechanisms,
including pivot bolts, may be utilized to facilitate actuation of
the first panel 14 relative to the frame 12. In other embodiments,
the first panel 14 is configured for rotation with respect to the
frame 12 by other approaches and structures. For example, pivot pin
assemblies can couple the first and second rails 40 and 42 and/or
top and bottom portions of the first stile 44 of the first panel 14
to the sill 20 and head 22 of the frame 12, respectively.
[0044] FIG. 6 illustrates the door 10 in the closed configuration
with both the first panel 14 and the second panel 16 in closed
positions. FIG. 6 also illustrates a lock or latch 70 of the first
panel 14 in accordance with examples. The latch 70 is coupled with
the first panel 14, and is generally configured to interface with
the sill 20 of frame 12 such that the first panel can be
selectively transitioned between a fully constrained configuration
(e.g., when in a closed position) and a partially constrained
configuration (e.g., when in an open position). In various
examples, in the fully constrained configuration, the first panel
14 is coupled with the frame 12 such that the first panel is
constrained against translation and rotation relative to the frame
12. In the partially constrained configuration, the first panel 14
is operable to be pivoted relative to the frame 12. The latch 70 is
therefore configured to provide users with the ability to
selectively decouple a portion of the first panel 14 from the frame
12 such that the first panel can be pivoted open relative to the
frame. In some examples, as discussed further below, the first
panel 14 can be selectively decoupled from the frame 12 at or
proximate the second stile 46 (i.e., the second side portion of the
first panel) such that the first panel is free to pivot relative to
the frame, such as about the hinges 60.
[0045] In various embodiments, the latch 70 includes a pin 72
mounted in an aperture 73 on the first rail 40 adjacent to the
second stile 46. In various examples, the pin 72 is operable for
actuation between a latched or engaged position, and a release or
disengaged position. When the first panel 14 is in the closed
position and the latch 70 in in the latched position, the pin 72
extends through the aperture 73 in the first rail 40 and into an
opening 74 in the sill 20 of the frame 12 such that the first panel
14 is fully constrained by the frame 12. FIG. 4A illustrates an
example of the opening 74 in the sill 20. In other embodiments,
(not shown), the opening 74 can be a structure in a strike plate on
the sill 20. When the latch 70 is in the release position, the pin
72 is withdrawn from the opening 74 in the sill 20 such that the
first panel 14 is operable to be pivoted relative to the frame 12.
Other embodiments of door 10 have other configurations of latches
or structures to releasably couple the first panel 14 to the frame
12. Although the latch 70 is shown on the rail 40 at the second
side portion of the panel 14 in the illustrated embodiment, the
latch is positioned at other locations in other examples. For
example, the latch 70 can be located on the frame 12, first jamb
24, or at other positions on the first rail 40. Various embodiments
can include one or more additional latches such as 70 on the first
rail 40, and/or on the second rail 42 to releasably engage the head
22 of the frame 12. Any such additional latches can operate in a
manner that is similar to or the same as the latch 70 described
above. FIG. 4B illustrates an opening 76 in the head 22 that can be
engaged by the pin of such an additional latch on the second rail
42 (not shown).
[0046] Second panel 16 is configured to translate by sliding and
pivoting with respect to the frame 12. In various embodiments such
as those shown in FIG. 7, the second panel 16 includes a plurality
of transfer mechanisms, such as for example riders 80A, 80B, 80C
and 80D, to provide the sliding and pivotal translation
functionality. As shown, riders 80A and 80B are situated opposite
one another along a top of the second panel 16. The rider 80A, for
example, may be situated at a top of the second stile 56 or may be
situated along the top rail 52 proximate the second stile.
Similarly, the rider 80B may be situated at a top of the first
stile 54 or may be situated along the top rail 52 proximate the
first stile in examples. Similarly, riders 80C and 80D are situated
opposite one another along a bottom of the second panel 16. The
rider 80C, for example, may be situated at a bottom of the first
stile 54 or may be situated along the bottom rail 50 proximate the
first stile. The rider 80D, for example, may be situated at a
bottom of the second stile 56 or may be situated along the bottom
rail 50 proximate the second stile.
[0047] In some examples, as discussed further below, the plurality
of riders 80A-80D are operable to slide and/or pivot within the
plurality of tracks 30A and 30B of the frame 12, and thus operate
to facilitate translation of the second panel 16 within the frame
12. In some examples, one or more of the plurality of riders
80A-80D are operable such that they can be actuated between release
or retracted states or positions, and transfer or extended states
or positions. As explained further below, by such a configuration
one or more of the plurality of riders 80A-80D are operable to be
retracted. When the one or more riders 80A-80D are retracted, the
second panel 16 can be at least partially decoupled from the tracks
30A and 30B of the frame 12 and thereby enabled to slide and pivot
relative to the frame 12.
[0048] As mentioned above, in various examples, the plurality of
riders 80A-80D are configured to be received by one or more tracks
30A and 30B of the frame 12. FIG. 8 shows the sill 20 of the door
10 with the rider 80D of the second panel 16 received within the
track 30A of the sill. Each of the plurality of riders 80A-80D is
optionally similar, or may differ as desired. In various
embodiments, one or more of the plurality of riders 80A-80D include
a bearing, a wheel, a pin, a bolt, a unidirectional roller bearing,
a multi-directional roller bearing, and/or an omnidirectional
roller bearing.
[0049] In various embodiments, riders 80B and 80C are substantially
similar and thus are described collectively with regard to rider
80B. In particular, riders 80B and 80C are operable and configured
such that they are retractable on the second panel 16. As such,
riders 80B and 80C can be retracted to partially decouple the
second panel 16 from the frame 12 such that the second panel can be
translated and pivoted relative to the frame 12. FIG. 9 shows rider
80B extending from the second panel 16, where the second panel
includes a first retraction assembly 82A operably coupled to the
rider 80B such that the rider can be extended and retracted
relative to the frame 12, according to some examples. A second
retraction assembly 82B shown in FIGS. 6 and 11 is substantially
the same as or similar to the first retraction assembly 82A, and is
coupled to rider 80C in a substantially similar manner to how the
first retraction assembly 82A is coupled to rider 80B.
[0050] As shown in FIG. 9, the first retraction assembly 82A
includes a rider control member 84, which is operably coupled to
rider 80B such that the rider control member can be actuated (e.g.,
by a user) to cause the rider to transition between a first
extended or transfer position (e.g., as shown in FIG. 9) and a
second retracted or release position. Rider 80B is shown in the
retracted or release position in FIG. 1, and it is to be
appreciated that rider 80C is similarly configured when
transitioned to the retracted or release position. In various
embodiments, the rider control member 84 is slideably received in a
rider control cutout 86. The rider control cutout 86 defines a path
88 that is traversable by the rider control member 84. The path 88
of the rider control cutout 86 is shown in FIG. 9 as being a
reverse "C" shape, although other paths are contemplated.
Accordingly, the illustrated example shown in FIG. 9 is not
intended to be limiting, but may include any suitable path operable
to be traversed by the rider control member 84 to cause the rider
80B to be transitioned between the extended or transfer positions
and retracted or release positions. In some examples, the path 88
includes a first portion 90 associated with the rider 80B being in
the extended position, and a second portion 92 associated with the
rider being in the retracted position. In the illustrated example
shown in FIG. 9, the path 88 includes a transition portion 94
linking the first and second portions 90 and 92. As shown, the
first and second portions 90 and 92 are angled relative to the
transition portion 94. It is to be appreciated that while the first
and second portions 90 and 92 extend substantially perpendicular to
the transition portion 94, the first and second portions may not be
angled relative to the transition portion, or may alternatively be
angled relative to the transition portion at any suitable angle,
provided that the rider 80B is selectively securable at each of the
extended and retracted positions. The rider control cutout 86 may
be formed directly in the second panel 16 (e.g., such as in the
first stile 54), or may alternatively be formed in a separate
housing 96 that is received by and/or secured to the second panel.
A linkage member (not visible) can couple the rider control member
84 to the rider 80B to couple the motion of the rider control
member to the rider.
[0051] In various embodiments, rider 80B is configured to slidably
couple the second panel 16 to the head 22 of frame 12 proximate the
first stile 54 (e.g., the first side portion of the second panel)
when the rider is in the extended or transfer position. In various
embodiments, for example, the rider 80B can extend into and be
guided for motion by the track 30B in the head 22. Conversely, when
the rider 80B is in the retracted or release position, the rider is
decoupled from the head 22 and frame 12 such that the second panel
16 is decoupled from the head proximate the first stile 54 (e.g.,
the first side portion of the second panel). Similarly, rider 80C
is configured to slidably couple the second panel 16 to the sill 20
of frame 12 (e.g., via track 30A) proximate the first stile 54 when
the rider 80C is in the extended position. Similarly, when the
rider 80C is in the retracted position, the rider 80C is decoupled
from the sill 20 such that the second panel 16 is decoupled from
the sill proximate the first stile 54.
[0052] With the riders 80B and 80C in the retracted positions, the
second panel 16 is decoupled from the frame 12 (e.g., the sill 20
and the head 22) proximate the first stile 54, such that the second
panel can slide and pivot relative to the frame via riders 80A and
80D. FIG. 3, for example, shows the second panel 16 in a
pivoted-open position as a result of the second panel being
decoupled from the frame 12 proximate the first stile 54. As shown,
the second panel 16 is slid from its closed position and pivoted
about the second stile 56. In various examples, the second panel 16
is slid and pivoted about the riders 80A and 80D, which are
configured to remain coupled with the frame 12 (e.g., the sill 20
via track 30A and the head 22 via the track 30B) while the riders
80B and 80C are decoupled from the frame.
[0053] FIGS. 6 and 10-12 illustrate hinges 100A-100C connecting the
first panel 14 and the second panel 16 in accordance with
embodiments. Although three hinges 100A-100C are shown and
described with reference to the illustrated examples, other
embodiments include more or fewer hinges. The hinges 100A-100C are
configured to be operable between disengaged or disconnected states
or positions, and engaged or connected states or positions, and to
thereby releasably pivotally connect the first panel 14 and second
panel 16. As described in greater detail below, when in the
disconnected states, the hinges 100A-100C disconnect the first
panel 14 from the second panel 16, enabling the first and second
panels to move independently of one another. When in the connected
states, the hinges 100A-100C pivotally connect the first panel 14
and second panel 16, enabling the first and second panels to pivot
with respect to one another about a folding axis defined by the
hinges.
[0054] In various embodiments, each of the hinges 100A-100C
includes a first mount 1021 and a second mount 1022, a first set of
leaves 1041 extending from the first mount 1021, a second set of
leaves 1042 extending from the second mount 1022 (two leaves extend
from each mount in the illustrated embodiment), and a pivot pin
106. The leaves 1041 and 1042 extend from their respective mounts
1021 and 1022 toward each other and into interleaved and
overlapping positions. Pivot pin 106 extends through the
interleaved leaves 1041 and 1042 and defines a pivot axis. The
first mount 1021 and second mount 1022 pivot or rotate with respect
to one another about the pivot axis defined by the pivot pin
106.
[0055] Hinges 100A-100C releasably connect the second side portion
of the first panel 14 to the first side portion of the second panel
16. In the illustrated embodiments, for example, when the hinges
100A-100C are in the connected states, the first mounts 1021 are
coupled to the second stile 46 of the first panel 14, and the
second mounts 1022 are coupled to the first stile 54 of the second
panel 16. In various embodiments, the hinges 100A-100C are
configured to be movable between first or retracted positions and
second or extended positions with respect to the first panel 14 and
second panel 16. The hinges 100A-100C can be configured for
operation in the disconnected states when in the retracted
positions. Conversely, the hinges 100A-100C can be configured for
operation in the connected states when in the extended positions.
Hinge retraction assemblies 112A-112C can be associated with the
hinges 100A-100C, respectively, and are operable to move the hinges
between the retracted and extended positions.
[0056] In various embodiments, the hinges 100A-100C can be housed
or garaged within the first stile 54 of the second panel 16 when
the hinges are in the retracted positions and disconnected states.
For example, the first stile 54 of the second panel 16 can include
first pockets or recesses 110 for the hinges 100A-100C. In the
illustrated examples, the recesses 110 are sufficiently large to
substantially or fully enclose the hinges 100A-100C (i.e.,
including both mounts 1021 and 1022) when the hinges are in the
retracted positions. The second stile 46 of the first panel 14
includes corresponding second pockets or recesses 114 for receiving
the mounts 1021 of the hinges 100A-100C when the hinges are in the
extended positions and connected states. In embodiments, the
recesses 114 are sufficiently large to substantially or fully
enclose the mounts 1021. FIG. 12, for example, illustrates hinge
100C in the extended position and in its connected state, with the
mount 1022 located within the recess 110 in the first stile 54 of
second panel 16, and the mount 1021 extending outside and beyond
the second panel into the recess 114 in the second stile 46 of the
first panel 14. For purposes of illustration, FIG. 11 shows the
hinge 100A in the extended position with the mount 1021 extending
from the second panel 16, but with the mount 1021 not in the
associated recess 114 of the first panel 14 (i.e., the hinge 100A
is not shown in its connected state in FIG. 11). Although hinges
100A-100C are described as being configured to be garaged on the
second panel 16 and movable between the retracted and extended
positions on the second panel in the illustrated embodiments, in
other embodiments the hinges can be configured to be garaged on
movable with respect to the first panel 14.
[0057] As shown in FIGS. 6, 11 and 12, the hinge retraction
assemblies 112A-112C each include a hinge control member 116 which
is operably coupled to the associated hinge (e.g., to the
associated mount 1022) such that the hinge control member can be
actuated by a user to cause the hinge to transition between the
retracted and extended positions. In various embodiments, the hinge
control member 116 is slideably received in a hinge control cutout
118. The hinge control cutout 118 defines a path 120 that is
traversable by the hinge control member 116. The path 120 of the
hinge control cutout 118 is shown in FIGS. 6, 11 and 12 as being
generally horizontal and linear, although other paths are
contemplated. Accordingly, the illustrated example shown in FIGS.
6, 11 and 12 is not intended to be limiting, but may include any
suitable path operable to be traversed by the hinge control member
116 to cause the associated hinge 100A-100C to be transitioned
between the retracted and extended positions. FIGS. 6, 11 and 12
show the hinge control members 116 in positions on the paths 118
that cause the associated hinges 100A-100C to be at the extended
positions. By actuating the hinge control members 116 (e.g., by
moving the hinge control members to opposite positions on the paths
118), a user can transition the associated hinges 100A-100C to the
retracted positions.
[0058] Embodiments of door 10 can include a latch 130 associated
with one or more of the hinges 100A-100C. A latch 130 is associated
with each of the hinges 100A-100C in the examples shown in FIGS. 6,
11 and 12. Latches 130 are operable to releasably connect or latch
the mount 1022 of the associated hinge 100A-100C to the second
panel 16 when the hinge is in either or both of the retracted
and/or extended positions, and thereby constrain movement of the
hinge in the second panel. In the illustrated embodiments, latches
130 are configured to releasably latch the mounts 1022 to panel 16
in both the retracted and extended positions. The embodiments of
latches 130 shown in FIGS. 6, 11 and 12, for example, include a
pair of spaced apart apertures 132A and 132B in the second panel
16, and a control member 134. Apertures 132A and 132B align with an
aperture in the mount 1022 (not visible in FIGS. 6, 11, 12) when
the mount is in the extended and retracted positions, respectively.
As shown for example in FIG. 11, when the hinge 100A is in the
extended position, the control member 134 can be inserted into and
extended through the aperture 132A and into engagement with the
aperture in the mount 1022 to constrain the mount 1022 to the panel
16 in the extended position. Similarly, when the hinge 100A is in
the retracted position, the control member 134 can be inserted into
and extended through the aperture 132B and into engagement with the
aperture in the mount 1022 to constrain the mount 1022 to the panel
16 in the retracted position. The latches 130 associated with one
or more of hinges 100B and 100C can be the same as or similar to
the latch 130 described above associated with hinge 100A. Yet other
embodiments include other latches having other structures to
provide functionality similar to or the same as that of the latches
130 described above.
[0059] Embodiments of door 10 can include a connector 140
associated with one or more of the hinges 100A-100C. A connector
140 is associated with each of the hinges 100A-100C in the examples
shown in FIGS. 6, 11 and 12. Connectors 140 are operable to
releasably connect the hinges 100A-100C, for example via their
mounts 1021, to the first panel 14 when the hinges are in the
extended positions, and thereby configure the hinges for operation
in the connected states by constraining the mounts in the first
panel. The embodiments of connectors 140 shown in FIGS. 6, 11 and
12, for example, include one or more apertures such as 142A and
142B in the first panel 14, and one or more control members such as
144A and 144B. Apertures 142A and 142B align with apertures 146A
and 146B in the mount 1021, respectively, when the mount is in the
extended position within the recess 114 in the first panel 14. When
the mount 1021 is located in recess 114 in this manner, the one or
more control members 144A and 144B can be inserted through the
apertures 132A and 132B and into the apertures 146A and 146B in the
mount, respectively, to connect the mount to the first panel 14 and
thereby configure the hinge in the connected state. The control
members 144A and 144B can be removed from the first panel 14 to
enable the hinges 100A-100C to be configured for the disconnected
states. Other embodiments include other connectors having other
structures to provide the functionality of the connectors 140
described above.
[0060] Other embodiments of door 10 include other structures for
releasably pivotally connecting the first panel 14 and second panel
16. For example, the associated leafs or other sections of one or
more pairs of hinge mount sections can be fixedly mounted to the
second stile of the first panel and the first stile of the second
panel, respectively, with the pairs of hinge mount sections
adjacent to one other and having knuckles or other structures that
can be joined by a pivot pin. The pivot pin can be inserted into
and removed from the adjacent hinge mount sections to releasably
pivotally connect the first panel and the second panel.
[0061] As described above, fenestration units such as door 10 can
be operated in one or both of the sliding mode and the folding
mode. For purposes of examples, the operation of door 10 in the
sliding and folding modes is described below as beginning and
ending with the door in its closed configuration. As shown in FIG.
1, for example, when the door 10 is in its closed configuration
both the first panel 14 and the second panel 16 are in closed
positions. The first panel 14 and second panel 16 form a barrier
within the frame 12 when the door 10 is in the closed configuration
in these examples.
[0062] During sliding mode operation of door 10, the first panel 14
can remain in its closed position, and the second panel 16 can
slide between its closed position and a sliding open position as
the door transitions between its closed configuration and sliding
open configuration. To configure the door for operation in the
sliding mode, the first panel 14 can be constrained to remain in
its closed position. In embodiments, for example, one or more
latches such as 70 can be actuated to the latched position and
couple the portion of the first panel 14 proximate the second stile
46 to the frame 12. When latches 70 are in the latched positions,
the first panel 14 is, for example, constrained against pivotal
motion about the hinges 60.
[0063] The second panel 16 is disconnected from the first panel 14
during sliding mode operation of the door 10. In the illustrated
embodiments, for example, the disconnected state of panels 14 and
16 can be caused by (1) actuating the connectors 140 to release the
hinges 100A-100C from the first panel (i.e., if the hinges were not
already in the disconnected states), (2) actuating the hinge
retraction assemblies 112A-112C to move the hinges to the retracted
positions on the second panel (i.e., if the hinges were not already
in the retracted positions), and (3) actuating the latches 130 to
latch the hinges onto the second panel at the retracted positions
(i.e., if the hinges were not already latched to the retracted
positions).
[0064] The second panel 16 of the illustrated embodiments is
configured for sliding motion with respect to the first panel 14
during sliding mode operation of the door 10. In the illustrated
embodiments, for example, the sliding configuration of the second
panel 16 can be caused by actuating the first and second retraction
assemblies 82A and 82B to move the riders 80B and 80C to the
extended or transfer positions in the tracks 30B and 30A,
respectively (i.e., if the riders 80B and 80C were not already in
the extended positions).
[0065] When the second panel 16 is configured for sliding motion,
the second panel can be slideably moved (i.e., slid) by a user
between the closed position shown in FIG. 1 and the sliding open
position shown in FIG. 2. In embodiments, the second panel 16 is
supported for sliding motion during the sliding mode by the riders
80A-80D. The riders 80A and 80B which are on the top portion of the
second panel 16 engage and are guided by the track 30B in head 22.
Similarly, the riders 80C and 80D which are on the bottom portion
of the second panel 16 engage and are guided by the track 30A in
the sill 20. In the illustrated embodiments, during an initial
portion of the transition from the closed position to the open
sliding position, the second panel 16 will be guided for motion by
the second portions 34A and 34B and third portions 36A and 36B of
tracks 30A and 30B, respectively, in a direction that is generally
transverse to the major planar surfaces of the first and second
panels, from the closed position coplanar with the first panel to a
position generally parallel to but not coplanar with the first
panel. During the remainder of the transition from the closed
position to the open sliding position in these embodiments, the
second panel 16 is guided for motion by the first portions 32A and
32B of the tracks 30A and 30B, respectively, in a direction that is
generally parallel to the first panel 14. The second panel 16 moves
about a path generally parallel to the first panel 14 as the second
panel transitions between its closed and open sliding positions in
the illustrated embodiments because the initial portion of the path
from the coplanar closed position to the position parallel and
adjacent to the first panel is relatively short and limited with
respect to the parallel portion of the path. In other embodiments
(not shown) the second panel 16 is not coplanar with the first
panel 14 when in the closed position, and the second panel moves
about a path parallel and adjacent to the first panel throughout
the transition between its closed position and open sliding
position. The second panel 16 can be transitioned from the open
sliding position (e.g., as shown in FIG. 2) to its closed position
(e.g., as shown in FIG. 1) by steps similar to those described
above, but in the reverse order and direction.
[0066] During folding mode operation of the door 10, the first
panel 14 and the second panel 16 are pivotally connected to one
another about a folding axis (i.e., in the connected state), and
fold with respect to one another about the folding axis as the door
10 transitions between the closed configuration shown in FIG. 1 and
the folding open configuration shown, for example, in FIG. 3.
Accordingly, to configure the door 10 for operation in the folding
mode, the first panel 14 is pivotally connected to the second panel
16. In the illustrated embodiments, for example, the connected
configuration of first panel 14 and second panel 16 can be caused
by (1) actuating the latches 130 to release the hinges 100A-100C
(i.e., if the hinges are latched to the retracted positions), (2)
actuating the hinge retraction assemblies 112A-112C to move the
hinges to the extended positions on the second panel (i.e., if the
hinges were not already in the extended positions), (3) actuating
the connectors 140 to connect the hinges 100A-100C to the first
panel (i.e., if the connectors were not already in the connected
states), and (4) actuating the latches 130 to latch the hinges onto
the second panel at the extended positions (i.e., if the hinges
were not previously latched at the extended positions).
[0067] The first panel 14 is configured for pivoting motion with
respect to the frame 12 during operation in the folding mode. In
the illustrated embodiments, for example, the first panel 14 is
configured to pivot by actuating the one or more latches such as 70
to the released position. The second stile 46 of the first panel 14
is thereby decoupled from the from the frame 12, enabling the first
panel to pivot about the hinges 60.
[0068] The second panel 16 is configured for both pivoting or
rotational motion with respect to the frame 12, and for sliding
motion with respect to the frame, during operation in the folding
mode. In the illustrated embodiments, for example, the pivoting and
sliding configuration of the second panel 16 can be caused by
actuating the first and second retraction assemblies 82A and 82B to
the retracted positions to move the riders 80B and 80C to positions
withdrawn from the tracks 30B and 30A, respectively (i.e., if the
retraction assemblies were not previously in the retracted
positions). When the second panel 16 is configured for pivoting and
sliding motion, the second panel is supported with respect to the
frame 12 by the riders 80A and 80D. The rider 80A which is on the
top portion of the second panel engages and is guided by the track
30B in head 22. Similarly, the rider 80D which is on the bottom
portion of the second panel 16 engages and is guided by the track
30A in the sill 20.
[0069] With door 10 configured for folding mode operation, for
example in the manner described above, the first panel 14 and
second panel 16 will fold with respect to one another about the
folding axis defined by the hinges 100A-100C as the door 10 is
transitioned to the folding open configuration shown in FIG. 3.
During this folding open transition of the door 10, the first panel
14 pivots or rotates about the hinges 60 with respect to the frame
12 as the first panel extends out of the frame. As shown in FIGS. 3
and 10, for example, the second stile 46 of the first panel 14
swings outwardly from the frame 12 during this pivoting motion
because the second side portion (e.g., the second stile 46) is
decoupled from the frame. Concurrently with this pivoting motion of
the first panel 14, the second side portion (e.g., the second stile
56) of the second panel 16 slides along the frame 12 toward the
first panel, and pivots with respect to the frame as the second
panel extends out of the frame. In the illustrated embodiments, the
sliding and pivoting motion of the second panel 16 are guided by
the riders 80A and 80D in the third portions 36B and 36A and first
portions 32B and 32A, of tracks 30B and 30A, respectively, as the
second panel moves from its closed position to its folding open
position. As shown in FIGS. 3 and 10, for example, the first stile
54 of the second panel 16 swings outwardly from the frame 12 during
this sliding and pivoting motion, at least in part because of the
pivotal connection of the first stile 54 to the second stile 46 of
the first panel 14 by the hinges 100A-100C. FIG. 3 shows the door
10 in is folding open configuration, with the first panel 14 is in
the folding open position and the second panel 16 in its folding
open position. Door 10 can be transitioned from its folding open
configuration to its closed configuration by moving the first panel
14 and second panel 16 from their folding open positions to their
closed positions by steps similar to those described above, but in
the reverse order and direction.
